Colchester County High School

The purpose:

Water penetration into classrooms alerted the

Ofsted “outstanding” rated Colchester County High

School for Girls in Essex to a problem with its roofs.

Its premises advisors, Archer Building Consultancy,

turned to Langley to offer technical support for the

most efficient best-value rectification, with funding

provided by the school’s governing body, The Alpha

Trust.

Our solution:

We carried out an in-depth roof condition report which highlighted

that the four flat asphalt and 10° pitched copper standing seam

roofs urgently need repair.

We advised the most efficient solution and use of resources was

to strip the copper roof back to the plywood deck and form a new

waterproof layer from our TA-30 Flat Roofing System and the

asphalt roofs overlaid with TA-30 and our Liquid Roofing System.

By leaving the original roof, we were able to minimise disruption.

In the process, we assessed the roofs for their suitability for

photovoltaic (PV) installation, then helped address energy costs:

one over a three-storey building was deemed appropriate. Finally,

in partnership with Archers, we supported the detail required to

apply for Salix funding to cover the supply and installation of the

PV array.
